Gasket Torque Formula
The following formula is used to calculate the Gasket Torque.
Tg =F*D*k / 1000
- Where Tg is the Gasket Torque (N-m)
- F is the bolt load (N-m)
- D is the diameter (mm)
- k is the nut factor (k-value)
To calculate the gasket torque, multiply the bolt load by the diameter, the multiply again by the nut factor, then finally divide by 1000.
How to Calculate Gasket Torque?
The following example problems outline how to calculate the Gasket Torque.
Example Problem #1
- First, determine the bolt load (N-m). In this example, the bolt load (N-m) is given as 50 .
- Next, determine the diameter (mm). For this problem, the diameter (mm) is given as 20 .
- Next, determine the nut factor (k-value). In this case, the nut factor (k-value) is found to be 40.
- Finally, calculate the Gasket Torque using the formula above:
Tg =F*D*k / 1000
Inserting the values from above and solving yields:
Tg =50*20*40 / 1000 = 40 (N-m)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:
bolt load (N-m) = 60
diameter (mm) = 40
nut factor (k-value) = 80
Enter these given values yields:
Tg =60*40*80 / 1000 = 192 (N-m)
